5. City growth may be thought of as a process of disorganization and reorganization. Growth always involves these processes to some extent, but when the city grows rapidly we see the disorganization assuming proportions which may be regarded as pathological. Crime, suicide, divorce, are some of the behavior problems in which social disorganization, when viewed from the personal side, expresses itself. The disappearance of the neighborhood and the local community with its personal forms of control is one of the immediate causal elements in this process.
